The work done in moving a unit positive charge between two points in an electric field is called:
A. Electric potential
B. Electric potential energy
C. Electric field intensity
D. Capacitance
Answer: Option A
Solution (By JKExamLibrary)
Electric potential V at a point is defined as work done per unit charge to bring a test charge from infinity to that point: V = W/q. Thus potential difference between two points is work per unit charge to move between them. Electric field intensity is force per unit charge; potential energy is work to assemble charges; capacitance is charge storage ability. Memory tip: 'Potential = work per unit charge; field = force per unit charge'. This definition-based question tests electrostatics fundamentals, frequently appearing in competitive exams. Always distinguish potential (scalar, work/charge) from field (vector, force/charge).
